We have a hot tub. Before we got it I had tried one at the motel a few times and they always made me hurt. Everyone said no, that's different, this won't. Well it's a long story, but we got such a good deal, we went for it. It helps in the very beginning when i get in for awhile. Then it makes me hurt again. I have FM and RA both. Have any of you had this experience? Everyone talks about long baths. But I haven't heard on hot tubs.
